An OTLP backend that happens to be in the EU.
Logs, traces and metrics over OTLP, in JSON or protobuf, straight from the exporter you already configured. No agent to install, no vendor SDK to adopt, and nothing that makes leaving expensive.
Three endpoints and no collector required
Point your exporter at our ingest host and set the header with your key. Traces become transactions and span groups, logs become log lines, metrics become rollups. If you already run a collector, keep it; we are simply another OTLP endpoint downstream of it.
Protobuf and JSON are both accepted on every endpoint, because half the language SDKs default to one and half to the other, and finding out which by trial and error is nobody idea of an afternoon.
Traces
POST /v1/traces. Spans are aggregated by shape; the interesting trees are kept whole.
Logs
POST /v1/logs. Severity, body and attributes, searchable next to your errors.
Metrics
POST /v1/metrics. Sums, gauges and histograms, cumulative or delta, rolled up per hour.
A cumulative counter is charted as change
An exporter reporting a cumulative sum sends a running total, and charting a running total produces a line that only ever goes up. Bugtail stores the difference between readings instead, handles the reset when a process restarts, and charts what actually happened in that hour.
No metric reading is ever a database row. An exporter reporting every ten seconds sends 8,640 readings per series per day; what is written is one row per series per hour. Series are capped per project too, because a label set is free text and somebody will eventually put a user id in one.
Questions people actually ask
Do you support the full OTLP specification?
Logs, traces and metrics over HTTP, in both encodings. gRPC is not supported; if that is a blocker for you, say so and we will tell you honestly whether it is on the list.
Can I send from a collector rather than from each service?
Yes, and it is usually the better arrangement. We are an OTLP endpoint like any other.
Fourteen days of Team, without a card.
Sign up with your work address, prove your domain with one DNS record, and paste a DSN. The first stack trace usually arrives before the coffee does.
No card. The trial ends by itself and drops to Free; nothing is charged unless you choose a plan.
